Operating Guidelines, Equipment & Safety Notes: The bare tool package includes the RY18CS20A-0 chainsaw unit, guide bar cover, lubricating oil bottle, and the adjustment tool nested inside the handle. Battery and charger are sold separately. Before making any cuts, apply a few drops of lubricating oil along the guide bar groove and onto the chain links. Check that chain tension allows approximately 1-2 mm of free play when gently lifted at mid-bar. Always wear cut-resistant gloves and eye protection. Remove the battery before performing maintenance, adjustments, or storage.
